Objectives

Powdery mildew is probably the most widespread vine disease. It is caused by a parasitic fungus (order Erysiphales). It significantly affects plant vigour, damaging leaves and stems, causing crop loss in extreme cases. Very vigorous plants are more susceptible to the fungus, which thrives in environments with high humidity and moderate temperatures. Although difficult to cure when well established, the disease responds well to several Integrated Pest Management (IPM) techniques. (see additional information field)

Additional information

IPM techniques are defined as good farming practices that alone or combined with adequate biocontrol agents (normally natural enemies of the disease) enhance crop health. They may also be applied as an alternative to chemical pesticides. The following four IPM measures can be applied (alone or combined) against this fungus:



The first measure is adequate pruning. Enhance plant ventilation and microclimate by removing the leaves surrounding the grape clusters, exposing the grapes to the sun. The number of leaves to be removed depends on local climate, trellis system and variety.



Reduction of the disease may be reinforced by using biological enemies such as the fungus Ampelomyces quisquali. This fungus parasitises on the Erysiphales fungi which cause powdery mildew. It should be applied in grape in pre and post-harvest, to attack the pathogen when it is hibernating.



Thirdly, combine forecasting models with local information on environmental conditions in the specific vineyards. This can greatly contribute to disease control and increase the accuracy of fungicide application.



The last measure is to use hybrid varieties of vines which are resistant to this disease, and are adapted to the market and local regulations, when they are available.
